APPARATUS FOR PRODUCING RAISED FIGURES IN CARPETS.

SPECIFICATION forming part of Letters Patent No. 568,300, datedSeptember 22, 1896.

Application iled February 28, 18976. Serial No. 581,162. (No model.) v

T0 all whom, it may concern:

Be it known that I, ROBERT ETHERINGTON, of the town of Paris, in thecounty of Brant and Province of Ontario, Canada, have 'invented acertain Apparatus for Producing Raised Figures in Carpets and SimilarWoven Fabrics, of which the following is a specification.

The object of my invention is to devise an apparatus for producingraised figures in carpets and similar woven fabrics; and it consists,essentially, in the peculiar construction, arrangement, and combinationsof parts hereinafter described and then definitely claimed for applyingtension 'to the ground-threads of the warp, so that the figure-threadsremain loose andpermitthe Woof-threads in the figures to rise above thelevel of the ground to form a raised pattern or iigure.

Figure l is a perspective view of a warping -box provided with myimprovements. Fig. 2 is a perspective view of the loom end used inputting my process into practice. Fig. 3 is a cross-section of thewarp-beam, showing, the iigurethreads overlying the ground-threads.

In the drawings like letters of reference indicate corresponding partsin the different figures.

A is awarping-box composed of suitable frames and side pieces.

B, C, and D are three reeds located, respectively, at the far end, themiddle, and the near end of the warping-box. These reeds are formed bythe vertical wires E, which run from top to bottom of each reed. In thedrawings only six such wires are shown in each reed, but for a fullsuper-weave about eight hundred and thirtysix wires would be used inreed B, or one for each warpthread, but in the other two reeds t'teen ortwenty warp-threads may be collected together and passed togetherbetween the wires. The warp-threads are passed from the spools on whichthey are usually wound between the wires .of the reeds B; the figure andground threads l-I and I between alternate wires. The figure-threads Hare preferably confined as to vertical motion by the leads F, while theground-threads I are free to pass up and down the full length of thereed. By so confining the figure-threads H the action of separating theligure and warp threads to pass on opposite sides of the roller G ismuch facilitated. This roller G has its spindle or bearing piecessliding in the slot a in the bearing-blocks J. The roller G rests upon aroller K,.which has its spindle or bearing pieces journaled in thebottom of the said slots.

L are two grooved pulleys journ aled at each end of the spindle of theroller G. Only one of these is seen in the drawings'.

Cords M are connected at one end to the reed B, pass over the groovedpulleys L, and have weights N hung at their other ends. These weightsthus serve to impart a downward pressure to the roller G.

At the front of the reed D is located the roller O, journaled inbearings P, which are slotted, as shown, so as to be adjustable, by

means of the bolts b.

It will be seen that after leaving the reed B the figure-threads II leaddirect through the reeds C and D and over the roller O, while theground-threads I pass between the rollers G and K and throu gh the reedsC and D below the roller O. Considerable tension is thus applied to theground-threads, causing them to tighten, while theA iigurethreads passthrough the warping-box quite loosely and are then wound upon thewarp-beam Q,which is shown in Fig. 2. As the figure and ground threadsare separated by the roller O it follows that on the warp-beam theiigure-threads overlap the ground-threads, as seen in Fig. 3.

In Fig. 2 is shown the end of the loom. Q is the warp-beam, the spindlec of which has been slipped into the bearings R. S is a ratchet-wheel onone end of the warp-beam, with which a dog d engages to hold thewarpbeam from turning. T is the iirst dead-rail, and U is the second,both being attached to the loom end by the brackets e and f. V is aroller suitably journaled in the bracket-s g. These brackets, it will benoticed, are slotted, so as to be adjusted vertically on the rail U bymeans of the bolts t'. From the warp-beam Q the iigure-threads H arecarried straight up and over the roller T, thence to the harness andworking parts of the loom, which are of the ordinary construction, and,not forming part of my invention, are not shown in the drawings. Theground-threads I pass under the dead-rail T, then back and over thedead- IOO rail U, thence passing to the harness with the figure-threads.The result of this arrangement is that a still further tension is putupon the ground-threads and the figure-threads made much looser thanbefore.

The essential parts of the mechanism used in my apparatus are thetension-rollers G and K, which tighten the ground-threads, theadjustable roller O, which may be set to permit the figure-threads topass clear of the roller G and which also separates the figure andground threads that they are wound in layers on the warp-beam, and theroller V, which guides the :figure-threads into the loom with a minimumtension, while a strong tension is put upon the ground-threads by thedead-rails T and U. As a result of this treatment of the ground andfigure threads the figure-threads, which are always brought to the uppersurface of the carpet in the figured portion thereof, allow the illingor woof threads to rise above the general surface of the carpet,producing a raised pattern.

Vhat I claim as my invention is- 1. An apparatus of the class described,con1- prising the loom end, a warp-beam journaled thereon twosuitably-supported dead-rails and a vertically-adjustable roller toseparate the ground and figure threads of the warp, substantially as andfor the purpose specified.

2. In an apparatus of the class described, the combination with awarping-box A, of reeds B, C and D connected with said box, a journaledroller K, a vertically movable roller G coactin g therewith, means forapplying pressure to said roller G, and a roller O adapted to separatethe ground and figure threads of the warp, substantially as and for thepurpose specified.

3. In an apparatus of the class described, the combination with awarping-box A, of reeds B, C and D connected therewith, a journaledroller K, a vertically movable roller G coacting with said roller K,means for applying pressure to said roller G, and avertically-adjustable roller O adapted to sep arate the ground andfigure threads of the warp, substantially as and for the purposespecified.
